Spontaneous perforation of the ureter diagnosed on technetium 99m DTPA excretory urography

A case of nontraumatic rupture of the ureter secondary to a nonopaque calculus is presented. Because of the inherent high image contrast caused by the leak of technetium 99m-DTPA-labeled urine, the technetium 99m DTPA excretory urogram is seen as an alternative to the intravenous urogram or contrast-enhanced computed tomography in selected cases of suspected ureteral rupture.     

Assessment of bioequivalence after subcutaneous and intramuscular administration of urinary gonadotrophins

The objective was to demonstrate bioequivalence between s.c. and i.m. administration of Humegon (FSH/LH ratio 1:1) and Normegon (FSH/LH ratio 3:1). In two randomized, single-centre, cross-over studies, 18 healthy volunteers on each formulation were assigned to one of the two administration sequences. Subjects were given single doses of one of the above gonadotrophins after endogenous gonadotrophin production had first been suppressed using high-dose oral contraceptive. Subsequently, rate (Cmax, tmax) and extent (AUC) of absorption of follicle stimulating hormone (FSH) and luteinizing hormone (LH) were determined for 14 days. For Cmax and AUC, analysis of variance (ANOVA) was performed on log-transformed data and for tmax ANOVA was performed on ranks. Intramuscular and s.c. injections of Humegon were bioequivalent with respect to the main pharmacokinetic parameters, being AUC and Cmax of FSH absorption. Intramuscular and s.c. injections of Normegon were bioequivalent with respect to the AUC of FSH and not bioequivalent with respect to the Cmax of FSH. For tmax of FSH as well as for most LH variables of both preparations, bioequivalence could not be proven due to the high intra- and interindividual variability and/or concentrations being close to the detection limit. Thus, the main pharmacokinetic FSH variables after i.m. and s.c. administration of Humegon and Normegon were bioequivalent.

Social anxiety spectrum and diminished positive experiences: theoretical synthesis and meta-analysis

Until recently, there has been limited recognition that diminished positive psychological experiences are important to understanding the nature of social anxiety. Meta-analytic techniques were used to evaluate the strength, consistency, and construct specificity of relations between the social anxiety spectrum with positive affect and curiosity. The social anxiety spectrum had significant inverse relations with positive affect (r=-.36; 95% CI: -.31 to -.40) and curiosity (r=-.24; 95% CI: -.20 to -.28). Relations between social anxiety and positive affect were stronger in studies sampling from clinical populations. Specificity findings (e.g., statistically controlling for depressive symptoms and disorders) further confirmed negative associations with positive affect (r=-.21; 95% CI: -.16 to -.26) and curiosity (r=-.21; 95% CI: -.08 to -.32). The literature on social rank, self-presentation concerns, self-regulatory resources, and experiential avoidance is reviewed and integrated to elaborate a framework of how, why, and when social anxiety may be inversely related to positive experiences. The specificity of theory and data to social interaction anxiety is supported by an examination of existing work on social performance/observation fears and other anxiety conditions. Overall, these findings highlight the importance of diminished positive psychological experiences in understanding excessive social anxiety.     

延边地区肺结核病人归口转诊模式的探讨

目的　分析延边地区建立肺结核归口转诊模式对肺结核病人的转诊到位率的影响,探讨提高转诊到位率的方法。方法 对全州8个县(市)医院、中医医院、中心卫生院、大型厂矿企事业单位职工医院的执法检查考核资料进行评价。结果 1.建立归口转诊模式前期转诊率为48.3%,转诊到位率为29.0%,后期转诊率为89.0%,转诊到位率为72.4%,有明显提高;2.前期年平均涂阳病人新登记率为13.36/10万,后期为17.86/10万,实施归口转诊模式前期与实施后期的指标有显著性差异(P<0.01)。结论 延边地区实施的肺结核病人归口转诊模式,对提高肺结核病的转诊到位率十分有效,应不断完善并深入推广。     

Sexual Healing: Daily Diary Investigation of the Benefits of Intimate and Pleasurable Sexual Activity in Socially Anxious Adults

A growing literature attests to deficits in social and romantic life quality in people with elevated social anxiety, but no research to date has explored how intense intimate encounters influence social anxiety symptoms. This study investigated whether the presence and quality of sexual activity on a given day predicted less social anxiety and negative cognitions on a subsequent day. We also explored whether the benefits of sexual activity would be stronger for more socially anxious individuals. Over 21 days, 172 undergraduate students described the presence and quality of sexual activity, social anxiety symptoms, and use of social comparisons on the day in question. Time-lagged analyses determined that being sexually active on one day was related to less social anxiety symptoms and the generation of fewer negative social comparisons the next day. Furthermore, more intense experiences of pleasure and connectedness during sex predicted greater reductions in social anxiety the next day for people high in trait social anxiety, compared to those low in trait social anxiety. These results were similar regardless of whether sex occurred in the context of romantic relationships or on weekdays versus weekends. The results suggest that sexual activity, particularly when pleasurable and intimate, may mitigate some of the social anxiety and negative comparisons frequently experienced by people with high trait social anxiety.     

复治肺结核病人的成因分析

目的　探讨复治肺结核病人形成原因。方法　使用调查表的方法 ,对前来诊治的复治涂阳肺结核病人的首次诊疗 ,管理情况进行问卷调查。结果　综合医院仍然为大多数患者的首次诊疗单位 ,因此部分肺结核患者未能得到正确的诊断、治疗和化疗管理。导致 67.2 %病人“中断”或“间断”治疗 ;另外结核病健康教育宣传做得不够 ,60 .3 %的患者诊断前未接受过防痨宣教 ,3 4.5 %的患者接受初次化疗时仍未得到宣教。这些均在导致复治病人的产生中起了重要作用。结论　加大DOTS覆盖面 ,加强归口管理力度 ,做好防治结核病教育工作是防止复治肺结核病人产生的重要环节。
